... Modifiers Crystal modifiers are special chemical structures produced synthetically to interact with forming wax aggregates. They usually consist of structures that have segments incorporated in them that interact with the forming wax crystals. These products act at the molecular level to alter...

... Abstract Paraffin crystal modifiers have been used very successfully over the past several years in oil field applications where paraffin wax is a problem. Paraffin waxes cause tubing and flow-line problems for many crude oil production companies. One of the major drawbacks of the type...

... ABSTRACT The present paper deals with the studies of crude oil composition, physicochemical characterisation of pour point depressants (PPD's) and waxes to know the specific & selective performance of PPD on crude for designing wax crystal modifier according to requirement. The study...

... ABSTRACT Selection of crystal modifier chemicals to reduce the pour point of paraffinic crude oils and to provide paraffin deposition inhibition has, in the past, been accomplished by laboratory physical testing. This paper presents a method for selection of these chemicals based on a technique...

... production of a well. This paper will describe a laboratory simulation of paraffin deposition used to evaluate two paraffin inhibitors in nine etudes. The two paraffin inhibitors evaluated were: (1) a blend of crystal modifiers in a controlled-release matrix form and (2) a commiercially available ethylene...
